2x+3≤x−5 solve for x

Mathematics
1 answer:
Westkost [7]3 years ago
7 0

Answer:

x≤−8

Step-by-step explanation:

2x+3≤x−5

Step 1: Subtract x from both sides.

2x+3−x≤x−5−x

x+3≤−5

Step 2: Subtract 3 from both sides.

x+3−3≤−5−3

Answer is

x≤−8

Write the equatoin of a graph that has Roots of x={-2,0,4} and has a point of (-1,10)
zheka24 [161]

Step-by-step explanation:

to have "roots" means that the function delivers 0 as function result for these values of x.

so,

f(x) = 0 for x = -2, x = 0 and x = 4

we can build this function as a product of factors.

each factor is an expression of x that turns 0 for the given value of x.

what is the simplest expression of x that turns 0, when x = -2 ?

well : x + 2

as you can easily see, this is 0, when x = -2.

and the easiest existing of x that is 0, when x = 0 ?

totally simple : just x.

and then x - 4 for x = 4

so, our function is

f(x) = x(x + 2)(x - 4)

but : this is one of infinite possibilities.

let's see what happens, if we use the x coordinate (-1) of the given point (-1, 10).

we know, the result must be 10.

-1×(-1 + 2)(-1 - 4) = -1×1×-5 = 5

aha ! so, in order to get 10 instead of just 5 we must multiply the whole thing by 2.

as n×0 is always still 0, this does not change our 0 points (or roots).

so, our full function is :

f(x) = 2x(x + 2)(x - 4)

or, if you need the function as a polynomial, we need to do the multiplications :

f(x) = 2x(x² - 4x + 2x - 8) = 2x(x² - 2x - 8) = 2x³ - 4x² - 16x

Find each one of the indicated angle measures.
PtichkaEL [24]

Answer:

∠5 = 71° & ∠8 = 109°

Step-by-step explanation:

∠1 = ∠5 (corresponding angle)

∠5 = 71°

∠5 + ∠8 = 180° (angles in a striaght line is 180°)

71° + ∠8 = 180°

∠8 = 109°

Carson has a package to mail. The package is 87 cm long. The shipping company only mails packages that are up to 35 in. long. Ca
m_a_m_a [10]

Based on the conversion done, the figure gotten is larger. Therefore, Carson cannot mail the package

From the information given, the package is 87 cm long.

Also, the shipping company only mails packages that are up to 35 in. long. Then, we convert inches to cm. This will be:

= 35 × 2.54 = 88.9 cm.

Therefore, he can't mail the package.
